With this thought in mind this inventionconwtemplates a comparatively simple unidue casing having a solutioncompartment with a fan and disc in combination therewith, and a crankfor rotatingthe fan and disc through gears wherein the disc turns slowand the fan relatively fast.

The object or this invention is, therefore, to

provide a unique hand operated mechanically actuated bubble makingmachine wherein a single crank operates a bubble d sc. at sl w sp ed anda fan at comparatively high speed.

Another object of the invention is to provide a mechanically actuatedbubble maker in which the parts may readily be cleaned.

A further object of the invention is to provide a mechanical bubblemaking machine which is of a simple and economical construction.

With these and other objects and advantages in View the inventionconsists of the new and novel combination, construction, and arrangementof parts as hereinafter more fully described, set forth in the claimsappended hereto, and disclosed in the accompanying drawings forming parthereof, wherein:

Figure 1 is a view showing a side elevation of the mechanical bubbleblowing machine.

The end plate Hl is providedwithfilling openings 24am} 25 and the" compartment 18 is filled untilthe liquid flows through these openings, and in the upper part of thepartition is an orifice 26 that is positioned to register with opening21 in the bubble disc I3, as shown in Figure 7. The partition 20 is alsoprovided with an arcuate web 28 which forms an air scoop that catchesthe air and directs it through the orifice 26.

The outer end of the shaft II is journaled in the partition 20 and theopposite end is rotatably mounted in flanges 29 and 3d of the gearsupport 31 which is mounted in the casing at the points 32 and 33, asshown in Figure 8. The crank I l is mounted on the end of a jack shaft34 which is ourna-ed in the flange 30 and also in an intermediate flange35, and the jack shaft 34 is provided with a gear element having a gear36 and a pinion 31 which is fixedly mounted on the shaft. The pinion 3Tmeshes with a gear 38 having a hub 39 through which it is fixed on theshaft H by a set screw 40, and as the crank is turned the shift [I isrotated at comparatively slow speed so that the disc l3 on the outer endof the shaft turns at slow speed.

The gear 36 meshes with a pinion 4| of a gear 42 that is freely carriedby the shaft H, and the gear 42 meshes with a pinion 43 of a gear 44that is freely mounted on the jack shaft 34. The gear 44 meshes with apinion 45 on a sleeve 46 which forms the hub of the fan l2 and with thehub freely rotatable on the shaft II, the fan will be rotated atcomparatively high speed. The gear support is provided with a bar 41which supports the intermediate flange 35, as shown.

With the parts arranged in this manner the compartment l8 may be filledwith a soapy solution or the like, and as the crank M is turned the fanand disc [3 will be rotated and as the disc rotates it will pick up afilm of the liquid which will cover the openings therein and the airfrom the fan will blow through the openings forming the film intobubbles which will float from the machine.

It will be understood that any suitable solution may be used and alsothat modifications may be made in the design and arrangement of theparts Without departing from the spirit of the invention.

What is claimed is:

1. A bubble blowing machine comprising a cylindrical casing having asolution compartment in one end, a longitudinally disposed centrallypositioned shaft journaled in the'casing, a disc having openings spacedfrom the periphery mounted on the shaft and positioned in the saidsolution compartment whereby the peripheral edge thereof passes throughthe lower part of the compartment as the disc rotates with the shaft, asleeve rotatably mounted on said shaft, a fan in the intermediate partof the casing carried by the sleeve and positioned to blow air throughthe openings of the disc and through the upper part of the solutioncompartment, and means rotating the fan and disc with the speed of thefan being greater than that of the disc.

, 2. A bubble blowing machine comprising a cylindrical casing having asolution compartment in one end, a longitudinally disposed centrallypositioned shaft journaled in the casing, a disc having openings spacedfrom the periphery mounted on the shaft and positioned in the saidsolution compartment whereby the peripheral edge thereof passes throughthe lower part of the compartment as the disc rotates with the shaft, asleeve rotatably mounted on said shaft, a fan in the intermediate partof the casing carried by the sleeve and positioned to blOW air throughthe opening of the disc and through the upper part of the solutioncompartment, a gear train positioned in the casing and rotatablyconnecting the sleeve to the shaft, and a hand crank extended from thecasing for rotating the shaft and disc through the gear train.

3. In a mechanically actuated bubble blowing machine, the combinationwhich comprises a cylindrical casing having a transverse partitionspaced from one end providing a solution compartment between thepartition and end of the casing, the opposite end of said casing beingperforated and the said partition and end of the casing from which thepartition is spaced having aligned openings therethrough, alongitudinally disposed shaft journaled in the casing, a disc havingopenings spaced from the periphery mounted on the shaft and positionedin the said solution compartment whereby the peripheral edge thereofpasses through the lower part of the compartment as the disc rotateswith the shaft said openings of the partition and end of the casingbeing in register with the opening through the disc, a jack shaft alsojournaled in the casing and spaced from the longitudinally disposedshaft, a, sleeve on the longitudinally disposed shaft having a fan onone end thereof, a train of speed changing gears mounted on the jackshaft, the longitudinally disposed shaft and sleeve, and a hand crankextended from the end of the jack shaft for rotating the longitudinallydisposed shaft with the disc carried thereon and the sleeve with the fancarried thereon with the fan rotating at a speed greater than that ofthe disc, said fan positioned to blow air through the openings throughthe partition, disc and end of the casing.
